Title: Improvements in speed-responsive control apparatus for engines
Inventor: GRANT THOMAS
IPC: F02D1/00
Filed: 1952-02-26
Abstract: 734,009. Fluid-pressure servomotor control systems. COCKBURNS, Ltd., and CAMMELL LAIRD & CO. (SHIPBUILDERS & ENGINEERS), Ltd. May 18, 1953 [Feb. 26, 1952], No. 4989/52. Class 135. A speed regulator for an engine is actuated by a spring-loaded piston 4 under the control of an engine-driven centrifugal device 15 and a valve 17 responsive to lubricating oil pressure, and, when overspeeding occurs, there is a large fall in oil pressure on the inlet side of valve 17 which opens and drains oil from under the piston 4. As applied to the control of the rack of a fuel injection pump 1, an engine-driven pump 7 supplies oil to the underside of piston 4 to act against the piston loading spring 9. The pressure of oil under piston 4 is controlled by a vent valve 21 in the centrifugal device 15 or by valve 17 which is normally kept in the raised, non-venting position by the pressure of the motive fluid (lubricating oil) acting on a piston 22. When the motive fluid pressure fails, a loading spring opens the valve 17, but the engine can also be shut down by depressing the valve by means of a knob 18. On over-speeding occurring, complete venting by valve 21 is assisted by the ejector action of a restriction 24. A relief valve 23 is connected in the conduit leading to the servomotor. 20 denotes a lubricating oil priming pump. Specification 495,358 is referred to.
Patent GB-536549-A (GB)
Title: Improvements in and relating to carburetters for internal combustion engines
IPC: F02M7/12
Filed: 1940-03-18
Abstract: 536,549. Spray carburetters. PICKERING, C. G. March 18, 1940, No. 4995. [Class 7 (iii)] In a carburetter as described in Specification 504,372, in which a heated mixture of fuel and primary air is admitted to a secondary air stream, and means are provided for obtaining a richer mixture and a larger inlet for the secondary air as the main throttle is opened, the inlet for admitting the heated mixture of fuel and primary air to the induction pipe is located on the engine side of the main throttle. Primary air admitted at 2 from the intake 3 flows past fuel nozzle apertures 31, 32, the mixture issuing by a pipe 10 leading to a heater, such as a jacket surrounding the exhaust manifold, or an electric heater, and returning by a pipe 11 and ports 13, 5a to the choke tube 5, where it mixes with secondary air from the intake 3. The openings 5a are arranged on the engine side of an eccentricallymounted throttle 6, which is actuated by suction and also by an arm 14 connected to the accelerator pedal. The spindle 7 of the throttle carries an arm 35 which moves, subject to the action of a spring 38, between stops 36, 37 on a cam 15, which in turn carries abutments 33, 34 co-operating with the arm 14 loose on the spindle 7. The cam 15, as the throttle is opened, operates an arm 16 to rotate the fuel nozzle 17 and alter the position of the orifices 31, 32 so as to give a richer mixture. The nozzle is surrounded by a sleeve formed with segments 26, 27, so that rotation of the sleeve by an arm 30 varies the effect of the primary air on the nozzle. Fluttering of the throttle valve is prevented by a dashpot 40 connected thereto by a rod 42 and arm 43. The main throttle may be arranged in the air intake 3 above the passage 2, the throttle 6 being then actuated only by suction.
